IMPRO'VED HEEL FOR BOOTS AND SHOES. m The Schedule referred to in-these Letters Patent and making part of the sama.

To whom it ma/y concern Be it known that I, GEORGE W. MARTIN, of the city` of Bostonfin the county of Suffolk, and State of Massachusetts, have, asI believe, invented new and useful Iniprovements in Detachable Heels for Boots and Shoes; and I dohereby declare the following io he a full and exact description of the same, reference being had to the awingstliat accompany and form a part of these specicatio'ns, in which igure 41 is a perspective view ofa heel entire.

Figure 2, the two parts of the heel separated, show-- ing screw and socket.'

Figure 3, sectional view cut on section of the heel-plate also.

Figure 4, modication o'i the screw-parts for fastening.

Figure 5,v section on line 3-4.

igure 6, section on line 5-6, andl illustrates the method of attaching the plate fr.

Letter A represents the base of a boot or shoe-heel.

Letter B, detachabl part of a boot or shoe-heel.

Letter c, heel-plate.

Letter d, a spindle, with screw-threads.

Letter e, socket, with female screw, to receive spindie d;

Letter f, a convex projection Von the outer end of the spindle d.l l

Letter g, a slight depression or concavity inthe bottom\ of the socket e. f

In fig. 4 I have illustrated a modication of the opposite, for the advantage of those who are prone to wear much more on one side than the other, or to turn the ankles either in o1' out.

In putting together the two parts A and B, iig. 2, the projection fwill meet the opposing surface of g before the two opposing siuiiices 0 O have come in contact;

screw d further advanced into the socket e, much pressthreads of d andje, so that the force required to turn B either forward or backward at thisjuncture will afford line l-2 showing crossbeing brought to position, as in iig. l.

In turning the two parts A and B together, the spindle j will reach and press upon the .bottom of the opening p before the two opposing surfaces O' and O have met each other. (See iig. 5 of drawings.)

'Now, as the spindle h is further turned 'into the socket i, pressure and friction will result both in the opening p, and between the threads of the spindle 7i and the socket i, suiiicient to retain the removable heel-piece B in place, and prevent'it irom being turned to the right or left by any concussion it would be likely to receive while in wear.

If these heel-pieces A and B are made of elastic material wholly, such as-rubber or the like,'or of anyplas- The part A may be made of leather, or any suitable iirm material, as, for instance, Wood, and the screwthread formed in any manner suitable to the nature. of the material used. Or, if .lesirnble, portions only of either A or B may be of elastic material, such as the Letter h is a hollow spindle, and has screw-threads on .both the inside and outside.

Letter i, the socket for h, and provided with screw- Letter j, a spindle'rising from the bottom of the socket'fi, and, in diameter, correspondingto the opening p in the spindle h. This will be oi elastic material, in length a little more than the depth of the opening p, and may be threaded, if thought desirable.

The metallic plates u c may be attached and secured to the parts A and B, either by screwsas l, 2, 3', 4, or by having the ope 6, 7 8, formed as in iig. 6, with the samemateri which thelieel-piece is formed, filling them, and these plates made still more secure byV the flanges x a', also illustrated in iig. (i.

The heel-plate c is secured in the same way, as may be seen in iig. 3.

his invention provides for the interchange of the .pressed forcibly into the openings 5, 6, 7, 8, which are not only larger at the outside, but have threads cuton their surface, as may be seen at z z in g. 6.

In the same manner is the plate c moulded in with its contacting parts, and held in the same way.

The iiange a: is applied as an auxiliaryto the above in holding in place the plate o or' the heel-plate c.

This method saves all screws and nails.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. An elastic boot or shoe-heel, when formed of thev two parts A and B, one provided with screw-spindle el, the other with screw-socket e, the threads of each bein formed by moulding-atthe same time and of the same the taste as to height of .heel or the width ofthe wearing-face thereof. Still further, the parts B may made with more fulness on one side than on the consequently, as the piece B is further turned and the ure will be produced, not only at g, but also on the v ample securityfor keeping the part B in place after once l tic material, they would be formed by moulding and v Y 2 material as the body of the part to which they belong7 arranged to operate as described :und for the purposes and provided, the one with the projection f, the other set forth.

with the depression g, to operate as described. 4. The manner of attaching the plete fv, as shown in 2. The part B, when its screw-spindle d is provided fig. 6, as also the plate c, shown in figs. 1 and with the proj ectionf7 and made of elastic materiel, and In testimony whereof, I have signed my name to the main .body-part thereof of non-elastic material, for this specication, in the presence of two subscribing the purposes described and set forth.
